Free Boiler 2015

Move the boiler in a house but be aware.

If the unit is in a kitchen cupboard, it takes valuable space. Boilers nearby the bedroom create annoying noise that disturbs to eventually hurt sleep. Some boilers are randomly attached at an inconvenient spot and don’t match the cosy home layout or pose a pure danger with exposed wiring or pipework, God, hope not.

Some (but not all) reasons for boiler relocation highlight:

Whether you want to move the boiler in your home for space, comfort, or aesthetics, there are things to consider, like a suitable new position, or probable difficulties during the moving process, etc. 

Boiler relocation is a complex task that might require specialised tradespeople and added costs. For details on funding, check if you qualify for a boiler grant via our boiler grant application.

So before you make any final decisions and start the renovation, there is a lot to go through. That’s why Boiler Grants made this detailed guide on moving boilers to answer common questions and help you figure out the approximate estimate of the expenses.

The Cost to Move a Boiler within a Property

Every home is specific, and different factors determine the cost of relocating a boiler.

Old or New Boiler

The cost varies whether you want to move your current boiler or install a brand new one. If you place a new boiler, the costs are from £700 to £2000 depending on its type, size, and whether or not you use financing or not.

How much to change the position of your existing boiler? 

It takes from £350 to £600 based on the distance. The price is lower if you want to relocate the boiler a short distance, such as at the same room or on the same wall. But if you need to move your boiler to another room or on another floor, then get ready to pay a higher amount of money.

The further you want to move the boiler, the more materials necessary, the higher expenses and the lower your property value goes, comments buy my house expert Paul Gibbens. 

Prepare to spend some extra money on unexpected complications or additional components. Common necessary extra parts are:

  • Pipework – to ensure access to a waste pipe;
  • Flue – so the boiler reaches a safe area outside;
  • Extension pipes;
  • More fittings and fixtures;
  • Controls (a digital thermostat);
  • Magnetic central heating filter.

Also, expect costs up to £3000 if you go from one type of system to another, for example, from a conventional one to a combi.

The value of moving a boiler includes the services of a professional engineer to execute the job. But, if your boiler is too heavy, this means more than one specialist is necessary. This also increases the charges.

Keep in mind that if the price to move your boiler goes up to £800 or more, it’s more beneficial to switch to a new one. Why not consider a more energy-efficient boiler?

How Long Does It Take to Move a Boiler

The time to relocate your boiler depends on the amount of work it requires. On average, relocating the boiler a few feet takes one day while moving it on another floor or room requires more labour and takes around 2 days to complete. That’s because it involves a lot of pipework. Alongside substantial distance, if any complications occur, the entire process takes even longer.

Moving a Boiler Regulations

It’s mandatory to install the boiler in a secure and convenient spot. Regulations require that:

  • The boiler is at least 1.2m away from a window or a door.
  • You connect it to a waste pipe to make sure it expels harmful and dangerous waste gases out of the home.
  • You flush the boiler system with clean water. This way you remove any sludge and guarantee improved performance. Sometimes this isn’t enough, so draining the boiler system is necessary at an additional cost.
  • You isolate the boiler.
  • You ensure easy access for an engineer to check on its compartments or alter its pressure.
  • You fit a carbon monoxide alarm.

Where to Position the Boiler

Here are some convenient locations with all the pros and cons to pay attention to:


  • Attic. It’s a good choice when you want the boiler to be out of sight. But if you decide, consider all the attic alternations that are necessary. This includes enough space, easy access for an engineer to maintain, well lit and safe floor, etc – all extra costs. Plus, a boiler in the attic means longer for hot water to reach downstairs, which is a waste of water and energy.
  • Bathroom. It’s a convenient location to ensure access to a waste pipe. However, some consider it a hazard to have an electrical appliance in a wet room. But there are measures to take and guarantee safety. Have a room sealed boiler installed in a cupboard and at a proper distance from taps, showers, or baths.
  • Utility room. Again, a perfect option to keep the boiler out of the way, ensure its outside access, and create pace elsewhere in your home.
  • Garage. It’s a suitable location to keep the boiler out of the property and have more free space. But you risk the boiler to freeze during cold months. So ensure frost protection and insulate the pipes with lagging. 


Move Your Current Boiler or Switch to a New One?

Before you relocate your old unit, there are essentials to consider. Is the renovation practical? Does it make financial sense?

If your existing boiler is relatively new and has 7-8 years of a 10-year warranty left, it’s reasonable to pay for a relocation. But if your boiler is old and has little warranty remaining, it makes sense to buy and have a brand new unit installed. This way you avoid payment of both moving a current boiler and then installation of a new one in just 1-2 years. If your unit requires specific parts that are expensive and hard to find, it’s again better to buy a new one and pay for its installation.

Think also about the financial benefit of a new A-rated (energy-efficient) boiler with a lengthy warranty. It’s an investment at first, but a new boiler saves up to £350 per year from electricity bills, so it pays for itself in a couple of years.

Moving to Another Property

Sometimes you might literally want to relocate your boiler to another property. If you have a long-lasting tenant story but for some reason you need to move out along with all your belongings, including appliances and heating, then it’s best to consult an expert, comments Ryan Banks of Fantastic Removals. Transporting sensitive and pricy gear is better off with additional delicacy, as a minor crack can lead to costly damage, especially with boilers, he adds.
